I did not think scalar x86 was that decode friendly, either.
The register names are not in a consistent location and can
even be split between a prefix and the "ordinary" placement.

Finding the start of instructions can be substantially
simplified with predecode adding a continue/start bit for
each byte. (Intel seems to manage even without this
assistance.)
